SPECKIFICATION forming part of Letters Patent N o. 648,664, dated May 1, 1900.

-Appiicaion inea April 2'7, 1899.

p To all whom, it may concern: Be it known that I, MATTHEW L. Horr, a

thin layers in which the separation is more rapidly and completely effected than when the liquid is acted upon in asingle body or mass. A contrivance of this general character is described in Letters Patent of the United 'States granted to me January 5, 1897, No.

574,607.r In the contrivance of this patent the blades are movably connected, so that they can be opened out or unfolded for cleaning when the device is removed from the bowl and so that the outer edges of the blades support themselves against the peripheral wall of the bowl when the device is in use.

The obj ect of the present invention is to support the blades when the device is in use rigidly and independent of the peripheral wall of the bowl,while the attachment of the blades fis such that they can be separated or detached for, cleaning when the device has been removed from the bowl.

In the accompanying drawings, Figure l is a vertical section of the bowl of a centrifugal `liquid-separator,showin g the general arrangement of the division contrivance, but omitting the registering devices and space-blocks of the removable blades. Fig. 2 is a horizontal section in line 2 2, Fig. 1. Fig. 3 is a horizontal section, on an enlarged scale, of a p0rtion of the division contrivance, showing the vregistering devices and space-blocks of the removable blades, the thickness of the parts and the spaces between the blades being eX- aggerated to represent the parts more clearly. Figs. et, 5, and 6 are detached perspective views of three blades constituting a group of removable blades, Figs. 4 and 6 representing, respectively, the front and rear plates of the group, and Fig.5 theintermediate plate.

Fig. 8 is a perspective view of the hook which is employed for removing the groups of removable blades from their supporting-frame. Fig. 9 is a horizontal section showing the blades of each group movably connected at their inner edges by links, the registering devices and the space-blocks being omitted.

Like letters of reference refer to like parts in the several figures.

A represent-s the bowl of a centrifugalliquid-separator, which may be of any usual or suitable construction. As shown in the draw'- ings, the bowl is provided with the usual removable cover B, which contains the escape-x pipes I) for the skim-milk and the cream-discharge b'. f

C represents the central feed-pipe, which projects through the neck of the coverv and is provided at its lower end with feet c, by which the lower end of the pipe is supported at a short distance above the bottom of the bowl. The lower end of the pipe is provided with an outwardly-projecting horizontal flange CZ. l

E represents upright wings secured to the outer side of the feed-pipe.

F F F2 F3 represent the blades or leaves of the division contrivance, which are arranged in an upright position in the liquid-space of the bowl. tially or eccentric around the axis of the bowl and are preferably curved, as shown, and ar- These blades are arranged tangenranged with their concave sides forwardly in the direction in which the bowl rotates, asindicated by the arrow in Fig. 2. Blades arranged in this manner intersect the radial lines of the bowl and greatly expedite and improve the separation. ploy curved' blades, l do not wish to limit myself to this form, as other forms may be employed. The blades or leaves are partly fixed blades and partly detachable blades. The xed blades F are secured at their outer edges to a surrounding cage or jacket G and at their inner edges to horizontal rings H, arranged one above the other. These fixed blades are arranged at such a distance apart that a group of detachable blades F' F2 F3 can be arranged While l prefer to emtoo v in the space between every two fixed blades.

` or jacket.

The number of detachable blades in a group may vary as circumstances may require, three being shown in each group in the drawings, of which the blade F is the front plate of thc group in the direction in which the blades rotate with the bowl, as indicated bythe arrows in Figs. 2 and 3, the blade F3 the rear blade, and the blade F2 the intermediate blade.

The inclosing jacket or cage may be constructed in any suitable manner. Asshown in the drawings, it is composed of upright bars g, abottom ring g', and horizontal curved rods or wires g2, connecting the bars g. The bars g restA against the peripheral wall of the bowl and center the contrivance in the bowl. This cage holds the outer edges of the blades at a 'short distance inwardly fromthe peripheral wall of the bowl, leaving a considerable space between said wall and the outer edges of the blades. This space permits of the free upward flow of the skim-milk along the inner side of the peripheral wall of the bowl and accommodates a considerable deposit of solid impurities, which is thereby prevented from clogging the spaces between the outer edges of the blades, from which the separated skimmilk issues through the openings in the case The inclosing cage or jacket G is rigidly connected by the fixed blades F with the inner rings H, these parts forming a -rigid annular frame having between the fixed blades eccentric upright spaces or pockets for the reception of the several groups of detachable blades.

The front. blade F of each group is provided on its rear side with a suitable number of rearwardlyprojecting pins or studs I, which pass through openings 'i in the intermediate blade F2 and the rear plate F3, one such pin or stud being shown on the plate in the drawings. These openings are so arranged in the several blades that when the three blades are engaged with each other by the studs andopenings the blades will stand in the proper relative position one slightly behind the other, or in echelon circumferenlltially, as shown in Fig. 3. These studs and 5,0'

^ tei'locking devices which enable the several lapenings form very simple and effective inblades of each group to be easily assembled 1nthe propery relation and which hold'the I blades rigidly in apposition and' prevent the y shifting of one blade on another in the surface direction of the blades.

These blocks are conveniently formedof rivets, which are secured in openings in these blades and have dat yheads of the proper thickness on Aboth sides of the blade. preferably form, ras shown, the corresponding space-blocks on the front side of the front blade F', and the'interlocking openings in the rear blade aro-formed -in the correspond- The heads of the interlocking studs ing space-blocks. Since the front and rear blades F F3 are provided with these spaceblocks on both sides, no space-blocks are required on the intermediate blade F2 and on the fixed blades F. The corresponding spaceblocks are arranged in the front and rear blades of the grnup in line with each other, so that the lpressure of one blade against the other falls upon the space-blocks on these blades and not upon the unsupported parts of the blades between the space-blocks, which would tend to indent the blades.

Means are provided for conveniently removing the detachable plates from between the fixed blades. The means shown in the drawings for this purpose are a hook L and openings Z, formed in the upper portions of the removable blades inline with each other, so that this hook can be inserted into these openings of the detachable blades constituting a group, and the latter can beraised by an upward pull. In order to expose these lifting-openings iu each group of `detachable blades, the fixed plate F, which lstands outside of said vgroup and in rear of the same circumferentially, and the group of detachble blades F F2 F3, which stand outside of this xed blade, are provided in their upper edges with notches Z', which stand in line with said lifting-openingsl and expose the same, as represented in Fig. '7.

When the division contrivance has been removed from the bowl, the removable blades are' readily withdrawn from the frame containing t-he fixed blades and can be separated for thoroughly cleaning the same. The frame and its blades are also easily cleaned,

as the spaces between the fixed blades are sufficient for that purpose.

The several blades constituting a group of removable blades can be connected at one edge by links m, as indicated in Fig. 9, so that the blades of each group are loosely connected in such a manner that they can be opened out or unfolded for cleaning.

I do not wish to claim, broadly, in this application an annular series of separable blades provided with interlocking devices which hold the blades rigidly in apposition, because such subject-matter is claimed in my application filed May 24, 1899, Serial N o. 718,003.
